Question

Hello people! Please Please can someone help me??? I really need some help with this question cause I dont understand anything... okay so the question is: Solve each of the quadratic equations below and describe what the solution(s) represent to the graph of each.
x^2 - 36 = 0 and x^2 = 8x - 12
Oh and please show work so I can understand whats going on...

Answer 1

x^2 - 36=0
or x^2 -6^2=0
or (x+6)(x-6)=0 or x=+6 0r -6

Answer 2

x^2 = 8x - 12
x^2 -8x + 12=0
or x^2 -6x -2x + 12=0
or x(x-6) -2(x-6) =0
or (x-6)(x-2)=0
or x=6 or x=2
hence from both the sol. of equation we have x=6

Answer 3

but wait could you explain the first one a little better? The second is perfect ( Thank you!) but I still dont see how you got the first questions answers.....

Answer 4

On the first one you could add 36 to both sides: x^2=36. Take the square root of each side and x=6 or -6.

Answer 5

oh ok i think i get it :) thanks!
